HUSETTS, A CORPORATION OF MASSA- AIR-DISTRIBUTER FOR OIL-STOVES.

Application filed September 11, 1919.

To all fao/'wm t may concern Be it known that I, FRED E. VHITE, acitizen of the United States, and resident of Gardner, Massachusetts,have invented certain new and useful Improvements in Air-Distributersfor Oil-Stoves, of which the following is a specification.

My present invention relates to improvements in air distributer-s foroil stoves and aims to provide a construction which will provide abetter supply and distribution of the air to the flame, in whichliability of impairment of the operation of the burner will be reducedto a minimum, and also to secure a device which may be manufactured at aminimum cost.

The invention includes the novel features of construction andarrangement and combination of parts hereinafter described Vand definedby the appended claims.

Embodiments of the invention are illustrated in the accompanying drawingin which Figure 1 is a central vertical section through the distributerassociated with a burner.

Fig. 2 is a detailwsectional view on line 2 2 of Fig. 1.

Fig. 3 is a view of a modification.

Referring by reference characters `to this drawing the inner wick tubeis shown at 1, the outer wick at 12L and the wick at 2.

These parts may be of the ordinary or any desired construction such asshown for example in Letters Patent of the United States granted October22, 1918, No'. 1,282,663. 4

3 designates my improved air distributer as a whole which is providedwith an annular horizontal shoulder 3a designed to overlie the upperedge of the wick and serve as a wick stop, the distributer having anannular depending flange or portion 3b adapted to telescope within theinner wick tube.

Immediately below the shoulder 3a the flange is preferably inclinedinwardly or slightly contracted and provided with annularly arrangedperforations as indicated at 3C. From the outer edge of the shoulder 3etthe distributer is extended substantially vertically to provide anannular perforated wall 3d, the upper end of which is con- Specicationof Letters Patent.

tinued upward in substantially,frusto-conical form as indicated at 3e,which portion is likewise perforated as shown.

At the upper end of this frusto-conical portion the metal is turnedinward into a horizontal plane as indicated at 3f to form a seat for thedistributer head, and this portion 3f is also preferably perforated at mas illustrated in the drawing.

The distributer head comprises a disk shaped portion 4 having an opencenter and an outer substantially vertical annular wall 4' suitablyperforated, the latter having preferably an outwardly turned flange orrim 4b to which the closing cap 5 of the distributer head .is connected,preferably by spinning.

The lower wall or bottom 4 of the distributer head is held spaced fromthe p0rtion 3f to provide an open annular air channel, and a convenientand economical manner of so holding it is to provide one of the walls(as for example 4) with a plurality of annularly arranged projections 4ewhich bear against the other wall, the parts being secured together byspinning the edges of the alining openings, the one over the other, asshown at y. The perforations in the portion 3f are preferably madelarger than in the frusto-conical wall to prevent liability of theirbecoming clogged, while at the same time the walls being parallel toeach other and the annular space therebetween entirely open except forthe space occupied by the projections 4c, permits the walls to belocated in comparatively close proximity and yet secures a substantialflow of air at reduced velocity. The bottom 4 of the distributer ispreferably inclined downwardly and outwardly which imparts a downwarddeflection to the film of air.

The locking skirt for holding the distributer in place within the wicktube is shown at 6. The distributer parts are customarily made of brass.The skirt I prefer te make of sheet steel in the form of a cylinderhaving the projecting locking tongues 6a designed, after the distributeris seated, to be moved into locking engagement with the locking bar 8 byrotary movement as described in the patent aforesaid.

To secure the skirt to the depending sleeve or flange of thedistributer, I provide l f l one of the parts as for instance the sleevewith openings 6b and punch the metal of the other part into theseopenings.

vInstead of joining the edges oi' the parts t ,and 3f as shown'in Fig. land relying on said latter member to admit air to the channel l mayleave said channel open at its inner periphery as shown in Fig. 8, the`connection between the parts l and 3f being Vmade at intervalsasillustrated in said ,fig-

ing an annular wall and a substantially horizontal annular portion atits upper part,

vand a distributer cap held above and spaced from said horizontalportion toV provide an ,air distributing space between vitself and saidhorizontal portion, said cap having an imperforate bottom wallprojecting` laterally beyond the said annular wall.

3'.- An air distributer for wick stoves having an annular perforatedwalland a substantially horizontal annular portion at its upper part, and adistributer cap having a downwardly and outwardly inclining imperforatevbottomV wall held aboveY and spaced from said horizont-al portion toform Van air distributing space, substantially as described.

I with annularly arranged perforations andV 4:. An air distributer forwicl'stoves having" an annular perforated wall and a substantiallyhorizontal top portion provided an open center, and a burner cap havinga bottom wall'providedY with an open center,

one of said walls having projections contacting with the other walltohold th'em spaced apart, and said parts being united at the edges oftheir open centers.

5. An air distributer for wick stoves having a Jl'rusto-conical upperperforated portion terminating in an inwardly extending horizontalportion at its smaller upper end, and a cap having its bottom arrangedabove and spaced apart from the said horizontal portion with means forthe passage of air tothe space between said bottom and the horizontalportion, the bottom of said distributer overhanging the wall of thetrusteconical part, substantially as described.

6L An air distributer for vwich stoves having a truste-conical upperperforated por- Vtion terminating Vin an'inwardly extending horizontalportion at'its Vsmaller upper end, and a cap having its bottomarranged'above and spaced apart from the said horizontal portion rwithYmeans Yfor theV passage of air to the space between said bottom and thehorizontal portion, the bottom of said distributer overhanging the wallof the rusto-conical part, and inclining downwardly and outwardly,substantially as described.

Y 7. An air distributer for wick stoves having a frusto-conicalperforated portion with an inwardly extending horizontal portion at thetop, an inwardly extending horizontal portion connected with therusto-'conical portion and forming a wick stop, a cap supported byV andspaced apart from the upper horizontal portion to forman air passagebetween'its bottom and the upper horizontal portion, said bottomoverhanging the Vfrusto-conical portion, substantially as described.

In testimony whereof I ailix my signature.
